Highlights

• MF-TDMA dual mode star/mesh link: same air interface as for star return link

• Multi-band, multi-beam and multi-satellite mesh operation (advanced option)

• Simultaneous star and mesh opera-tion

• Separate IFL for mesh receiver (for multi-band and/or opposite polariza-tion operation)

• Mesh signaling in accordance with DVB-RCS standard

• Fully dynamic mesh capacity as-signment

• QoS support for mesh traffic

The transparent mesh option allows the SatNet S5200 to be part of a peer-to-peer overlay network, in which terminals communicate directly with each other through the satellite transponder. This cuts in half both the transmission delay and the bandwidth occupied by such traffic, bringing advantages for both communications quality and cost; the greatest benefits are achieved for delay-sensitive real-time applica-tions such as voice.

Mesh-equipped terminals can communicate simultaneously with other mesh terminals and with the hub; adding the mesh option does not affect the conventional DVB-RCS functionality and the mesh functionality is a fully backwards-compatible extension of the DVB-RCS standard. Within the mesh overlay part of the system, the primary functions of the hub are to allocate bandwidth to terminals and to control and manage them.

This mesh network functionality is called “transparent”, because it operates through a conventional satel-lite transponder. In other words, it does not need any specialized on-board processing. When used in con-junction with a suitable hub such as the SatNet mesh-enabled hub, the S5200 terminal supports connec-tivity limited only by the space segment design: it supports single-beam configurations, multi-beam con-figurations with different cross-strapping constraints and even multi-satellite configurations. The mesh and conventional “star” operation can be on different polarizations and/or in different frequency bands.

Advanced DVB-S2 Solution

The new DVB-S2 standard offers very significant bandwidth savings in the outbound link of DVB-RCS systems, com-pared to the current DVB-S standard. The simplest form of DVB-S2 is known as Constant Coding and Modulation (CCM). This is a direct replacement for DVB-S, but offers a 30% better bandwidth efficiency, thanks to the use of so-phisticated channel coding techniques. The SatNet terminal supports CCM as well as DVB-S. With the Advanced DVB-S2 option, the SatNet S5300 supports two additional, advanced modes of DVB-S2 known as Variable Coding and Modulation (VCM) and Adaptive Coding and Modulation (ACM). The choice between the latter two is usually driven by system characteristics such as frequency and precipitation statistics. All three forms of DVB-S2 (CCM, VCM and ACM) have been adopted by the DVB-RCS standard. DVB-S2 terminals are thus fully interoperable.

VCM allows optimization of the transmission parameters used for each termi-nal, so that the link budget — and hence the achievable bandwidth efficiency — is no longer driven by the worst case terminal in the system. Differences that can warrant such optimization include dish size, location in satellite beam and prevailing local rain statistics. Depending on system characteristics, a VCM system can achieve a gain in bandwidth efficiency of close to 50% over a DVB-S system.

ACM takes this optimization further and allows variation in time of the modu-lation and coding used for each terminal. The adjustments are based on feed-back reports of the terminal’s received signal quality. This ability to respond in real-time eliminates the need for fixed system margins for e.g. rain fade and interference. The margin savings can be converted to increased band-width efficiency. Depending on system characteristics, the gain over CCM systems can reach 50–100%.

Besides VCM and ACM, the Advanced DVB-S2 option offers additional valuable features: • Symbol rates of 128 kBaud – 45 MBaud • Support for 16APSK modulation, for extremely high bandwidth efficiency • ACM quality feed-back through satellite return link signalling or dial-up telephone line.

The Pay-as-You-GrowTM approach enables service introduction with very small initial investment and preserves the investment as the system expands. Initially, when the number of deployed terminals is very small, the per-user cost of a full-featured hub that supports demand-assigned management of the return link bandwidth can be significant. In such small networks, it can be beneficial to defer the cost of the full-featured hub and accept temporarily a potentially less efficient return link bandwidth utilization. In SatNet’s Pay-as-You-GrowTM concept, this is achieved by implement-ing the return link as a form of single-channel-per-carrier (SCPC) operation; i.e., using semi-permanent, continuous connections from each terminal to the hub. When the number of deployed terminals grows, the hub and terminals can be upgraded to fully DVB-RCS compliant, demand-assigned operation.

The forward (outbound) link is shared among the terminals in the same manner in all stages of the Pay-as-You-GrowTM evolution of the network.

The SatNet S5400 fully supports the Pay-as-You-GrowTM concept. It can be deployed as an SCPC terminal, and later upgraded to full DVB-RCS functionality simply by configuring the software over the air. No hardware modifications or upgrades are necessary. The change can even be completely transparent to the end user.
